[1.1.4] possible NPE: multi-monitor: initScreens: mouse check

[Ronny]

Hi,

I use 3 monitors in win 7 with sikulix-api 1.1.4 (This version was built at 2019-02-27_17:37 (Build 212) )

now if i start a new screen (screen = new Screen() ). I get a NullPointerException if my Mouse is in the 3rd Screen (windows screencounting) in the middle of the monitors. Is the mouse at this time on Screen 1 oder 3 (right and left outside) is all fine...

The code is simple:

public ScreenRobot() {
    screen = new Screen();

Exception in thread "main" java.lang.NullPointerException
 at org.sikuli.script.Location.getScreen(Location.java:130)
 at org.sikuli.script.Mouse.move(Mouse.java:391)
 at org.sikuli.script.Mouse.move(Mouse.java:372)
 at org.sikuli.script.Mouse.init(Mouse.java:60)
 at org.sikuli.script.Screen.initScreens(Screen.java:136)
 at org.sikuli.script.Screen.<init>(Screen.java:169)
 at de.sm.ScreenRobot.<init>(ScreenRobot.java:31)

please use:

public ScreenRobot() {
    Debug.on(3)
    screen = new Screen();

and analyse/post the log

... I currently do not have any multi-monitor environment available, sorry.
